I am trying to set up a Elasticsearch cluster but right now I am confused over configuring of master node and data node. So my doubt is I want to have 3 nodes(all master eligible) , so according to minimum no of master node I should update the min count as 2. Now the confusion is If I initialize 2 nodes as master stating master: truedata: false. Then all I am left is a single data node, which is not fine.
So I am thinking if its possible that master node can also work as data node. As one node I will keep as master and second node will behave as both master and data by stating master: truedata: true and third node will be purely data node.
Is the configuration possible. Will be needing the help from experts present in this community to get the most desired solution.
